Exact Solutions to the Fermion Propagator Schwinger-Dyson Equation in Minkowski space with on-shell Renormalization for Quenched QED
Shaoyang Jia, M. R. Pennington
With the introduction of a spectral representation, the Schwinger-Dyson equation (SDE) for the fermion propagator is formulated in Minkowski space in QED. After imposing the on-she…
Pascalutsa-Vanderhaeghen light-by-light sumrule from photon-photon collisions
Ling-Yun Dai, M. R. Pennington
Light-by-light scattering sumrules based on general field theory principles relate cross-sections with different helicities. In this paper the simplest sumrule is tested for the $I…
-wave from decay data at BaBar and classic Meson-Meson scattering from LASS
A. Palano, M. R. Pennington
A recent analysis of data on the two photon production of the and its decay to has determined the -wave amplitude in a "model-independent" way assuming primar…
How gauge covariance of the fermion and boson propagators in QED constrain the effective fermion-boson vertex
Shaoyang Jia, M. R. Pennington
We derive the gauge covariance requirement imposed on the QED fermion-photon three-point function within the framework of a spectral representation for fermion propagators. When sa…
Landau-Khalatnikov-Fradkin transformation for the fermion propagator in QED in arbitrary dimensions
Shaoyang Jia, M. R. Pennington
We explore the dependence of fermion propagators on the covariant gauge fixing parameter in quantum electrodynamics (QED) with the number of spacetime dimensions kept explicit. Gau…
Gauge covariance of the fermion Schwinger-Dyson equation in QED
Shaoyang Jia, M. R. Pennington
Any practical application of the Schwinger-Dyson equations to the study of -point Green's functions of a field theory requires truncations, the best known being finite order per…
